To'q ZZ it concern:

Be itknown that I, CLARENCE PdBnoN- State of NewYork, have invented certain new and useful Improvements in .Socket-' Wrenches, of which the following is a specification My invention relates to socket-wrenches such as are ordinarily used in connect-ion with automobiles and gasolene engines and similar cont-rivances. 1

The object of my invention is to provide a combination of socket wrenches or a nest of socket wrenches which are adapted toifit a. number of burs or nuts of difi'erent sizes, the smaller the largest size being fastenedto a stem.

'-A. further object of-my' invention is to provide a handle for said stem that can be folded up into line with said stem and positively' held there-while said handle is being ;used as a flat wrench, for which the stem and socket wrench then becomes the handle, the-handle having theshape of a fiat wrench, being provided at each end with the jaws thereof and with recesses intermediate of said ends.

A further object of my invent-ion is to permit the handle being extended tran ovide a suf-.

versely to the stem so as to ficient leverage for turning sai wrench, and a nut in engagement therewith.-

Further objects of my invention will appear in the specification and drawings, the novel features thereof being properly pointed out in the claims at the end thereof, it bein understood that various changes in the erm, proportion and minor details of construction may be resorted to without de-.

- parting from the spirit or sacrificing. any

of the advantages of this invention.

Fig. 2 is a section on the line 2"2 in Fig. l, the handle being shown in full lines Figs. 3' and 4 are views of bushings intended to be used with one of the sockets-for the purpose of taking up the clearance between it and a nut' which is to be turned thereby. Fig. 5

- shows a modification of the handle and stem of the socket jwrench,'showing a construction by which the leverage on the socket wrench may be increased. Fig.- 6 is a side elevation of the part shown in'Fig. .5. Fig. 7 is a detail view of the parts shown in Fig. 6 with the handle turned down to horizontal position. Fig. 8-is a side View of the parts shown in Fig. 7.

In the accompanying drawings like refereiice characters refer to like parts.

My improved wrench con ists of a main body portion or socket 1 which is preferably of hexagonal shape, although the-number of sides on the socket constitutes-no necessary part of my invention. This main body portion has a cone shaped end 2 to which i;- attached'a stem 3, this stem being integrally attached thereto, as shown in Figs. 1 and 2, and pivoted thereon as shown in Figs. 5, 6, 7 and 8, for a purpose which will presently be described. The stem 3 is slotted at 4.. as

is indicated in cross section in Fig. 2, and in such slot at the end is provided a screw or pin 5 having a head 6 on one end thereof. the other end thereof being threaded and being provided with a thumb nut 7. On this pin 5 the handle 8 is mounted, the handle being slotted at 9 so as to permit longitudinal adjustment thereof on the pin 5.

The handle may be set in the position shown in Fig. 1, in which position it may be clamped by the thumb nut 7, or it ma he slid eit-herto the right or to the left and used in such position -to turn the socket wrench.- The handle is provided with the alligator. jaw 10 at one end and 'with the square opening 11 adjacent thereto, and is provided at the other end with the hexagonal opening '11 and the forked opening 12. The'handle with either of these openings may be'used as'fa fiat wrench, either sepa- '2 intense used as a flat wrench the main body portion of the wrenchca'nbe used as a handle there for, materially increasing the leverage thereof, and the construction-by which this result is secured I will-now describe.

At the bottom of the slot 4 I provide a lug 14, with which either the opening 10 or the opening 12 at the ends of the handle is adapted to engage. F ortliis purpose the handle may be rotated to the dotted line position shown in Fig. l and moved endwise so that the inner end of the handle engages with said lug, whereupon it may be clamped in that position by means of the-thumb nut 7. While in that position the wrenchas a whole may be applied to 'a nut, for example 15, and the socket or body por tion of the wrench-may then be used as a handle for the purpose of turning such nut by the wrench.

Carried on the main body portion of the socket wrench is the spring 16 having a' pin 17 mounted. thereon, which pin passes through the perforations 18 in the various sections of the socket wrench. It will be understood from an inspection of Fig. 2 that the main body portion or the outer socket is rigid with the handle or stem, and that nested within su'clr socket is shown three other sockets progressively reduced in size so that the one fits snugly within the other. Each of these sockets is perforated at two places with the holes 18, so that each of said sockets in turn may be moved to either the inner or the outer position, in either of which positions it can be held by the pin 17. It will thus be seen that the particular socket which is of the same size as the nut which is to be turned can be moved to the extended position and fastened'in such position, and canbe used accordingly, or the inner sockets may be removed, in which case the socket that is of the proper size for use can be used in its innermost position for the purpose of turning the nut. In case the socket does not make a close fit, a bushing 19, such as is shown in detail in Figs. 3 and 4 and in position'in the extended socket in Fig.- '2, may be inserted in said socket for the purpose of taking up the extra space be tween such socket and the nut to be turned. These bushings are preferably of fiat metal made U-shaped,. ith the ends turned out, and are intended to fit the socket closely and are of sufiicient thickness to take up the clearance between the socket and the nut. It will be understood that one side of the bushing 19 may be omitted if desired.

It will be seen that a number ,of'sections or sockets may be provided, each of which in turn may be thrown to operative position and held firmly, in said operative position while it is bei ng used, and when it -is desired to change one section-for another the v pin 17 maybe quickly moved out to permitthe readjustment of the inner section, after which they may be again looked in'their readjusted position.

In Figs. '5, 6, 7 and 8 I haveshown a modification of my improved wrench. In

a reduced end 120, and the handle or stem 3 terminates in the forked'end 21 which is pivoted on, said reduced end by means of the pin 22. "The reduced end 20 has a vertieal slot therein as indicated at 23, which permits a slight movement of the handle up and down thereon, the pin 22 being permitted to move up and down by the length of the' slot minus the diameter of the-pin. lhis permits the handle to be turned down tothe position shown in Fig. 8, thus increasing the leverage of the handle on the socket. Tihe handle 8 can engage with the stem 2 in the same way "as it engages with.

it in the construction heretofore described, the stem 3 being in each case provided with,,

the lug 4 with which the handle can engage. It will also be understood that the reduced end 20 has its ends narrowed at the top, 'as' shown at 24, andv the stem 3 has'a recess therein corresponding therewith to fit on said projection 24:, into and out of engagement with which it can be moved by-a longitudinal movementof the stem when-the parts are in the position shown in Figs, 5

.and 6.

It will thus be seen that my improved wrench is capable of use in a great variety of ways, all of which. uses are secured by the construction heretofore described.

Having thus d scribed my invention, what I claim as new and s ate? table is as follows:

1. In a wrench the combination of a main body portion having a socket therein, a series of graduated sockets nested therein, a perforation through the outer socket, aseries of perforations .in in each of the inncrqsockets, said inner sockets each being separately movable to an inner ,or outer. position, and a pin passing through the perforation in the outer section and engaging with one ofthe perforations'in each of said inner sockets to hold each of said inner sockets in its inner or outer position, said socket-s being separately or collectively removable from said main body portion on the withdrawal of said pin, aspring or other flexible mount-ing attached to the socket on.the main body rtion for supporting said pin and yieldiigly holding it'in place.

2. The combination in a tool, of a'handle having a slot therein open at one end, a pin in the outer end of said handle across said slot,'alug projecting across said slot at the line therewith 'this form the body portion 1 terminates in end thereof opposite said outer end, a pivoted slotted member mounted on said pin, said member having at its opposite ends open ended heads, said pivoted slotted member being capable of being swung about said pin, into alinenient with said handle and moved lengthwise to engage one of its open ended heads with said lug to permit the other open ended head to be used as e tool with the rest of the tool as a handle therefor.

In testimony whereof I affix my signature in presence of two Witnesses.
